江南有射工毒虫，一名短狐，一名蜮。常在山间水中，人行及水浴。此虫口中横骨角弩
，唧以射人形影则病，其诊法。
初得或如伤寒，或似中恶，或口不能语，或恶寒热。四肢拘急，旦可，暮剧。困者三日
，齿间血出，不疗即死。
其中人有四种，初觉则遍身体视之。其一种正黑如墨子，而绕四边者人或犯之如刺状。
其一种作疮，疮久即穿陷。一种突起如石之有棱。其一种如火灼人肉， 起作疮。此种最急
，并皆杀人。居溪旁隰地，天大雨，或逐人行潦流。入人家而射人，又当养鹅鸭，亦可以食
人，行将纯白鹅以辟之。白鸭亦善，带好生犀角，佳也。
若见身中有此四种疮处，便急疗之。
急周绕遍，去此疮边一寸，辄灸一处百壮，疮亦百壮则瘥。
又方，赤苋茎叶，捣，绞取汁，饮之，以滓敷之。姚云，服七合，日四五服。
又方，葫蒜，令敷以拓疮上，灸蒜上千壮，瘥。
又方，白鸡矢白者二枚，以小饧和调，以涂疮上。
又方，鼠妇，虫，豉各七合，巴豆三枚，去心。合猪脂，但以此药涂之。
又方，取水上浮走豉母虫一枚，置口中，便瘥。云此虫正黑，如大豆浮水上相游者。
又方，取皂荚一梃，尺二者，捶碎，苦酒一升，煎如饴，去滓，敷之痛处，瘥。
又方，马齿苋，捣饮汁一升，滓敷疮上。日四五遍，则良验。
又方，升麻，鸟 各二两，水三升，煮取一升，尽服之。滓敷疮上，不瘥，更作。姚同

姚云此虫含沙射人影便病，欲渡水，先以石投之。口边角弩发矢，言口息两角能屈伸。
冬月则蛰。
有一长角横在口前，弩檐临其角端，曲如上弩，以气为矢，用水势以射人。人中之，便

江南地区有一种名为“射工”的毒虫，别名短狐、蜮。这种虫子常栖息在山间的溪流中，当人走路经过或下水沐浴时，它口中横生的骨角状弩机，会喷射出无形的箭矢攻击人的影子从而致病。其诊断方法如下：
刚发病时，症状有的像伤寒（外感风寒所致的疾病），有的像中恶（突然感受秽浊邪气所致病证），有的不能说话，有的怕冷发热。四肢拘挛紧急，早晨较轻，傍晚加重。病情严重的三天内，牙齿间出血，若不治疗就会死亡。
人被这种虫子咬伤后，主要有四种表现，初觉时全身仔细检查可见：其中一种颜色正黑如墨点，周围有一圈红晕，触碰时感觉像被针刺一样；另一种形成疮疡，时间久了就会溃烂凹陷；第三种突起像石头一样有棱角；第四种像火烧皮肤一样，红肿起疮。这几种情况中最危急的是最后一种，都会导致死亡。这种虫子居住在溪边低湿之地，天降大雨时，或随行人脚步溅起的水流移动。它们进入人家攻击人，因此应当饲养鹅鸭，也可以食用鹅鸭肉，出行时可携带纯白色的鹅来辟邪。白鸭也有类似功效，佩戴生犀角也是好的预防措施。
如果身上发现这四种疮处，应立即治疗。
急救方法：在疮口周围遍身灸治，距离疮边一寸处，每处灸一百壮，疮口本身也灸一百壮，即可痊愈。
另一个方子：取赤苋菜的茎叶，捣碎，绞取汁液饮用，并将药渣敷在患处。姚氏说，服用七合，每天服用四五次。
又一个方子：用葫蒜（大蒜），捣烂敷在疮上，并在蒜上灸一千壮，可愈。
又一个方子：取两只白色鸡粪（白鸡矢白），用麦芽糖调和，涂抹在疮上。
又一个方子：取鼠妇（潮虫）、豆豉各七合，巴豆三枚（去心）。混合猪脂，仅以此药膏涂抹患处。
又一个方子：取水面上漂浮游动的豉母虫一枚，放入口中嚼服，即可痊愈。据说这种虫子通体漆黑，像大豆大小浮在水上游动。
又一个方子：取一尺二寸长的皂荚一根，捶碎，用醋一升，煎煮至像饴糖般稠厚，去掉药渣，涂抹在疼痛处，可愈。
又一个方子：取马齿苋，捣碎取汁饮用一升，药渣敷在疮上。每天四五次，效果良好。
又一个方子：取升麻、鸟喙（川乌头）各二两，水三升，煮取一升，全部服下。药渣敷在疮上，若未痊愈，再制作服用。姚氏观点相同，另外增加犀角二两。
姚氏说，这种虫子含沙射人影便致病，想要渡水时，先向水中投石。它口边的角弩发射箭矢，意思是它的口和两边的角能屈伸。冬天则蛰伏不动。
它有一只长角横在口前，弩檐覆盖在角端，弯曲形状如同弩机，以气息为箭矢，利用水流之势射击人。人一旦被射中，就不能说话，其他症状与葛洪所述一致。
In the Jiangnan region, there is a venomous insect known as "Shegong" (Arrow-throwing Gong), also called "Duanhu" (Short Fox) or "Yu" (Hidden Archer). This insect often inhabits streams in mountainous areas. When people walk by or bathe in the water, it uses a bony, crossbow-like structure in its mouth to shoot invisible projectiles at a person's shadow, causing illness. The diagnostic method is as follows:
Initially, symptoms may resemble Taiyang disease (a syndrome caused by external pathogenic factors affecting the Taiyang channel), or Zhong'e (sudden illness due to foul turbid pathogens), inability to speak, or aversion to cold and fever. The limbs become stiff and cramped; symptoms are milder in the morning and severe in the evening. In critical cases, bleeding occurs from between the teeth within three days, and death ensues if untreated.
There are four types of lesions after being bitten by this insect. Upon initial detection, one should examine the entire body. One type appears black like ink dots with a red halo around the edges, feeling like a needle prick upon touch. Another type forms an ulcer that eventually perforates and sinks. A third type protrudes like a stone with sharp edges. The fourth type resembles skin burned by fire, presenting as redness and swelling. Among these, the last type is the most acute and fatal. These insects dwell in low, damp areas near streams. During heavy rain, they may move with splashing water or runoff. They can enter homes to attack humans. Therefore, raising geese or ducks is recommended; consuming goose or duck meat is also beneficial. Carrying pure white geese while traveling can ward off evil. White ducks are also effective. Wearing raw rhinoceros horn is considered good for prevention.
If any of these four types of sores appear on the body, immediate treatment is required.
Emergency treatment: Moxibustion should be applied all around the affected area. At each point one cun away from the sore, apply 100 moxa cones (Zhuang). Apply 100 moxa cones directly on the sore as well, which will lead to recovery.
Another prescription: Take the stems and leaves of Amaranthus tricolor (Chixian), crush them, squeeze out the juice, and drink it. Apply the residue topically. Yao states to consume seven he, administered four to five times daily.
Another prescription: Use garlic (Husuan), crush it, and apply it to the sore. Perform 1,000 moxa cones on the garlic until healed.
Another prescription: Take two pieces of white chicken droppings (Baijishi Bai), mix with maltose syrup, and apply to the sore.
Another prescription: Take Porcellio scaber (Shufu, woodlice) and fermented soybeans (Chidou), each seven he, along with three seeds of Croton tiglium (Badou, removing the heart/core). Mix with lard and apply only this ointment to the affected area.
Another prescription: Take one Daimother insect floating on the water surface, place it in the mouth, and chew/swallow it for recovery. It is said that this insect is jet black, about the size of a soybean, floating and swimming on the water.
Another prescription: Take one stick of Gleditsia sinensis (Zaojiao, Chinese honeylocust pod), one chi two cun in length, crush it, and decoct with one sheng of vinegar until it becomes thick like maltose syrup. Strain and apply to the painful area for recovery.
Another prescription: Take Cimicifuga foetida (Shengma) and Aconitum carmichaelii (Wutou, bird's beak), each two liang, with three sheng of water. Decoct to obtain one sheng, and consume entirely. Apply the residue to the sore. If not healed, prepare again. Yao agrees but adds two liang of Rhinoceros Horn (Xijiao).
Yao states that this insect causes illness by shooting sand at a person's shadow. To cross water, one should first throw stones into it. The arrow-shooting mechanism at the corner of its mouth implies that its mouth and lateral horns can flex and extend. In winter, it hibernates.
It has a long horn extending horizontally in front of its mouth, covered by a bow-guard at the tip, curved like a crossbow. It shoots using breath as arrows and water momentum as force. Once hit, the victim cannot speak, and other symptoms align with Ge Hong's description.
